Resilient bar a bit loose?

Hanging some resilient bars for the first time. I'm attaching them on the thick metal flange but this leaves the other side loose by design. The other side seems to move a bit with weight so I don't understand how they can support drywall?

What is a resilient bar? Is this the strips used to mount sheetrock for soundproofing? If it is they must move a bit. It's their job to isolate the movement of the sheetrock from the studs. I've never used them but I imagine it will all firm up when you get the entire wall sheet rocked.

Thats how and why it works. You install rc channel perpendicular with 1 screw per joist. Once you screw sheetrock to it, its flat and evenly 1/2" below the joists. You dont screw through the drywall and into any wood or you defeat the purpose. The leading edge is loose but the next one picks up the weight of the drywall so that the last one doesnt sag. Drywall is flat. So all the rc channel will be flat once you screw it all together.
